Field Master Pro

Handheld Spectrum Analyzer delivers the highest continuous frequency coverage up to 54 GHz and real-time spectrum analysis bandwidth up to 110 MHz to address current and emerging applications

Frequency Range: 9 kHz to 9/14/20/26.5/32/43.5/54 GHz

Anritsu’s Field Master Pro MS2090A real time spectrum analyzer delivers performance never previously available in a compact, handheld instrument. With continuous frequency coverage from 9 kHz to 54 GHz, the Field Master Pro MS2090A is specifically designed to meet the test challenges of a full range of other wireless technologies in use today, including: 5G, LTE, wireless backhaul, aerospace/defense, satellite systems, and radar.

The Field Master Pro MS2090A delivers the highest levels of RF performance available in a handheld, touchscreen spectrum analyzer, with a displayed average noise level (DANL) of -164 dBm and Third Order Intercept (TOI) of +20 dBm (typical). This makes measurements such as spectrum clearing, radio alignment, harmonic, and distortion even more accurate than previously possible. For modulation measurements on digital systems, 110 MHz modulation bandwidth coupled with best-in-class phase noise performance maximizes measurement precision, while ±0.5 dB typical amplitude accuracy provides confidence when testing transmitter power and spurious.

Ruggedized for field use, all versions provide a comprehensive range of features to speed and simplify measurement, as well as enhance usability. RTSA spans of 22 MHz to 110 MHz (option dependent) provide capability for cellular interference monitoring to full ISM band signal analysis. In addition to being a full span swept tuned spectrum analyzer, all versions include a spectrogram display that helps monitor the RF spectrum for intermittent or interfering signals. Integrated channel power and occupied bandwidth measurements simplify the measuring and characterizing of common radio transmission. Cable and Antenna line sweep measurements are supported with the addition of the S331P Site Master. IQ data capture of 5G frames enables the capture and saving of IQ data for off-line processing on a PC using standard data analysis tools.

PC based IQ analysis software for use with IQ data captured from a Remote Spectrum Analyzer

IQ Signal Master MX280005A Vector Signal Analysis Software provides a comprehensive suite of measurements that deliver post processing and analysis of IQ data files captured on the Field Master Pro spectrum analyzers. The software is designed to bring together all the essential tools required to capture IQ data files and then gain critical insights into the nature of the captured signals. Modes within the application, support the ability to capture or stream IQ data into the PC memory, perform modulation quality measurements, playback IQ data with high frequency and time resolution, view LTE and 5G frame resource blocks and playback IQ spectrograms from up to four analyzers in parallel.

A file conversion mode allows IQ data captured on the supported analyzers to be converted to the format required for playback using a Vector Signal Generator MG3710E further enhancing the overall capability.

The software is designed for national RF spectrum regulators, security agencies and defense electronics companies who need to gain critical insight into RF signals that have been captured in the field. It is also suitable for organizations that need to monitor and protect RF spectrum from unlicensed operators or unintended sources of interference

The 5G Evolution of Indoor Wireless Networks for Smart Buildings and Manufacturing Facilities

5G technology has introduced some exciting possibilities for in-building functions. The “smart” buildings and manufacturing facilities of tomorrow will include new functions such as IoT, factory automation, machine learning devices, and cloud compute applications. To handle these new features, network architectures will change, frequency bands will be added, and new network features will be introduced. In this webinar, we will examine how the indoor wireless networks will evolve as we move to 5G, and the challenges in managing these complex networks to ensure performance and reliability for both commercial as well as the public safety networks.

Understanding Real-Time Spectrum Analysis

Real-time spectrum analysis (RTSA) provides signal insight previously only available in high-end lab and benchtop solutions. RTSA allows gapless capture and display of rapidly changing and highly intermittent signals. The digital nature of RTSA also makes a variety of analysis and display technologies possible that traditionally required multiple hardware platforms.


Delivering the highest levels of performance available in a handheld RF spectrum analyzer, the Field Master Pro MS2090A instrument gives field engineers and technicians unparalleled measurement accuracy previously reserved for only benchtop instruments.

  • Interference hunting and spectrum clearing – fast sweep speeds a low distortion front-end and the Real Time spectrum analyzer combine to quickly identify interfering signals. A special interference finder option adds AM/FM demodulation with audio output plus interfering source triangulation on a digital map to pinpoint and identify the location and source of interference.

  • Broadcast transmitter analysis – a comprehensive range of transmitter measurements – including: AM/FM modulation quality measurements, harmonic, spurious, occupied bandwidth, channel power, and adjacent channel power – ensures conformity to regulatory requirements.

  • Microwave radio links – with a frequency option up to 54 GHz and exceptional sensitivity for dish alignment, power and modulation bandwidth can be verified during installation or maintenance testing with a waveguide horn antenna.

  • Satellite system monitoring – ideal for monitoring downlink signals to search for interference and noise

  • Pulse Radar Measurements - The wide bandwidth of the MS2090A enables detailed analysis of pulsed radar signals. In zero span, resolution bandwidth can be set as high as 40 MHz (option dependent), enabling a sweep time as low as 60 ns and amplitude measurements of pulses as narrow as 20 ns.
